MCB is Miniature Circuit Breaker which is thermal operated and used for short circuit protection in small current rating circuit. Normally it is used where normal current is less than 100A.
MCCB is Moulded Case Circuit Breaker and is thermal operated for over load current and magnetic operation for instant trip in short circuit condition. Under voltage and under frequency may be inbuilt.
